T-Mobile confirms Android 10 for OnePlus 6T and OnePlus 7 Pro1
However, this does not guarantee that carriers will release the Android 10 update at the same time or at all. Luckily, T-Mobile recently confirmed (via AndroidSoul) it has agreed to release the OnePlus 6T Android 10 update when it's ready.
Also, a more recent OnePlus smartphone, the 7 Pro will receive the update as well. Unfortunately, the update is still in development, so we're not sure if they're still on track for an October release. As we reported several days ago, the unlocked OnePlus 7 and OnePlus 7 Pro are already getting the Android 10 update.
We'll keep an eye out on T-Mobile's support website for more details on the OnePlus 6T and OnePlus 7 Pro Android 10 updates, although we don't expect them to be available by the end of the month.
